“理性”与“合作”：行为经济视角下的人性假设

摘要

The compatibility of ＂rationality＂ and ＂cooperation＂ is the essential question of behavioral sciences and the boundary between traditional economics and behavioral science.Many researches show,behaviors of reciprocity and cooperation are not only related to the approaches and environment of behaviors but also have their inner physiological basis.Although there are many evidences that do not support the Rational Person Hypothesis,we can＇t deny the value of Economic Man Hypothesis in theory as well as in practice,whose inner core topic is to understand the nature of Economic Man.Therefore,from the perspective that Behavioral Economics is the revision of the Mainstream Economics,it is the Hypothesis of Economic Man not the Rational Person Hypothesis that can explain the question of ＂rationality＂ and ＂cooperation＂ better.%理性与合作是否相容是行为科学的根本问题,也构成了传统经济学和行为经济学的分野。许多研究表明,互惠与合作行为的发生不仅与行为的方式、环境有关,且具有内在的生理基础。但并不能因为不支持理性人假设的证据的出现而否定经济人假设在理论和实践中的价值,其内在的核心命题在于理解经济人假设的本质。因此,从行为经济学对传统经济学修正的意义上,经济人假设比理性人假设更好地回答了人类行为的最初动机,是解释理性与合作问题的一种可能的途径。
